I thought 100% load is 100% load, but maybe I am wrong?

post #1 of 5
Thread Starter 
So I have been using TAT, Coretemp, and Speedfan to monitor my temps while I clocked my 6420 up to 3.1GHz. I have a so-so cooler so I wanted to make sure my load temps were low.

Well I finally got to 3.1GHz and ran orthos for 8 hours and my temp never went above 45C.

Here is the weirdness. TAT has this option to 100% load each individual core. So next to Core 0 there is a start 100% load and then next to Core 1 there is a start 100% load thing. When I run use this feature my cores run as hot at 52-53C.

I reran Orthos on the Gromacs Core test again and sure enough speedfan shows 100% CPU use but my temps are 43-45C.

So what gives? Is TAT doing something MORE intensive, since it is Intel's tool? Anyone else near their OC'ed computer with TAT who can try it and confirm similar results?

TAT makes your cores run hotter, but I don't know the reason.

Comparing to all the things I do, folding 100% while playing an intense game, my temps are exactly the same as Orthos loads. So, I would not use TAT to run my cores.

Yes it is.. it like stresses CPUs to 150% usage or something. So if your temps are good in TAT which yours are you know you are 100% safe as long as vcore is at least 1.48 or lower (1.50 is too much for my blood)

i would assume that tat is doing a more robust, indepth test.

Okay thats good to know. I am currently on 1.36v so I don't think I have anything to worry about. My RAM is the reason I can't overclock anymore right now, but I am not looking to get any more anytime soon.
